RREGATINGDHYDRANT'.

SPECPICATON forming part o Letters Patent No. 391,475, dated October 23, 1888.

Application filed May 22, 1888. Serial No. 274,692. (No model.)

To all whom, it may concern:

Be it known that l, WILLIAM LACY, J r., a citizen of the United States, residing at Los Angeles,.in the county of Los Angeles and State of California, have invented a new and useful Improvementin Irrigating-Hydrants, ofwhich the following is a specification.

The object of my invention is to construct a simple, neat, and convenient stop-valve or f1tting for hydrants, adapted to allow the escape of a large volume of water and effeetually shut the same off when desired.

Afurther object is to devise a tting of this kind which can be readily attached to ordinary sheet-iron pipe; also, to provide neat, cheap, simple, and efficient means for breaking the velocity of the discharge as the water flows from pressure-pipes.

My'invention comprises the combination of a hydrant head or collar having a dischargeopening' therethrough, the lower part of which opening is contracted to form an offset around the inner wall of the opening, below the mouth thereof; a vertical hydrant-pipe fitted into the contracted part of the head or collar and projecting above the offset to form, with the walls of the head, an annular channel between the pipe and the walls of the head or collar; a compressible ring greater in thickness than the depth of the annular channel, seated in the channel to serve as a gasket; a dome or top concave on its under side and larger in diameter than the discharge-opening in the hydranthead, secured to the head and elevated a short distance above the mouth of the dischargeopening and approximately axially coincident therewith; an approximately unobstructed space between the head and'dome or top; a threaded valve stem passing through and screwing into a threaded opening in the center of the top, and a valve swiveled upon the lower end of such valve-stem to lit upon and close the opening in the head.

The accompanying drawings illustrate my invention.

Figure 1 is a vertical midsection of my improved hydrant. Fig. 2 is a plan of the hydrant with the top cut away on line x a, Fig. 1.

B is the head of the hydrant, having an opening, C,'therethrough, which is contracted in the lower part thereof to form the offset D.

The opening below the offset is of such size as to fit snugly upon the end of the pipe A, which is riveted or otherwise secured within the opening C, and projects a short distance above the offset D to form an annular channel between the pipe and the walls of the head to contain the rubber ring K, which forms a seat for the 4valve J.

E is the top of the hydrant, and is concave upon its under side to direct the water downward as it issues from the pipe. 'llhe top E is secured to the head B by bolts F, passing through the flange G and the ferrules H and screwing into the under side of the top E. The ferrules H hold the top at the desired distance above the head. The edge of the top projects beyond the flange G, so as to give direction to the stream of water after it liows out of the pipe. The valve is mounted. in the center of the top E, through which the screwstem I passes, and it screws up and down within the opening C.

The valve J is swiveled within the stem I in the ordinary manner by means of a pin, L, passed through the boss on the valve, and a channel, M, in the stem, so that when the valve is screwed down upon its seat it will not turn upon and wear the seat. IVhen the valve is raised, as shown in Fig. 1, the water will flow up and will be distributed around the mouth of. the pipe by the concave top E, and will flow off in a smooth even stream. IV hen the valve is screwed down upon the seat formed by the rubber ring and the end of the pipe, a tight joint is formed. In case the rubber ring becomes worn it may be removed-.aud replaced by a new one.

Now, having described my invention, what I claim as new, and desire to secure by Letters Patent, is-

The combination set forth of the hydranthead havingadiseharge-opening therethrough, the lower part of which opening is contracted to form an offset around the inner wall of the opening, below the mouth thereof, a vertical hydrant-pipe fLtt-ed into the contracted part of the head and projecting above the offset t0 form,with thewall ofthe head,`an annular channel, a compressible ring greater in thicknessV than the depth of the annular channel, seated in such channel, the top, concave on its under IOO side and larger in diameter than the discharge- I opening in the center of the top, and a valve opening in the hydrant-head, secured to the l swiveled upon the lower end of such valvero head and elevated a short distance above the stem.
